I finally have learned how to build a square tube exhaust system
that
wraps and curves anyway I want.  I am going to build another MM
(number
4) for my airplane using the wide MMP.  The exhaust system will
fit
inside the mount. It will lay beside the wedge oil  pan but far
enough
off to allow for heat shielding.  It can be built out of .063 321
sheet
for around $250 (materials) which I think is not bad.  If the 2000
degree SS turns out to be for real, thinner sheet may be possible.

  Ed Klepies and I will be getting together after the holidays.
His
airport is less than 2 Tailwind  hours away.

  Shop wiring will be finished today.  Hook up before the end of
the
month. There is much to do to make the shop fully  functional,
but I
will be working on the rotary installation as soon as the power is
turned on.

Jerry,
Is this a VAM style muffler?
George (down under)

No,  I don't  have room for a VAM.  Jerry

Jerry you may have missed this. Do you have any old muffler systems
that I can
have or buy for the dyno engine?

Sorry Paul,  I cleaned out what I thought was useless  junk before the
move.   How soon do  you need it.  I may make a 304 version of the
square one before committing the bucks to the 253.   Jerry

For the dyno all I need is mild steel. Two pipes 32 inche long.
I'll do a sketch.
